My bother was day one 2077 player on steam. but he felt dizzy when playing 2077. So he only played 6 hours. then I continue played 2077 by using his account. right now, the DLC releases, I just want to buy the 2077 and DLC on my steam account, so I do not need switch account every time when I want to play 2077. but I do not want to give up my 160-hours game saves. so How can I transfer the game save from my bother's steam account to my steam?ps:I play 2077 on my pc. so the saves is on my pc.
